This commits moves the single use of that property to the already
existing Tomcat-specific one.

This commit auto-configures a prototype `RSocketRequester.Builder` bean
for building requester instances. This builder is pre-configured with
auto-detected `RSocketStrategies` (same as the server side).

This commit restores the read-only `finalName` so that its value can
be lazily resolved against `${project.build.finalName}`.

While doing the evaluation ourselves and not relying on a dedicated
field at all would have been better, the evaluation increased the
number of required dependencies for no good reason.

IDEs should not offer auto-completion for that read-only field and it
is not published in the generated site either.

This reverts commit 3b4ff7d7.
The commit caused the build to fail because it disabled
`@ConfigurationPropertiesScan` completely in slice tests. It
did not take into account components that were explicitly included
in slice tests using the `components` attribute. Since `@ConfigurationPropertiesScan`
replaces `@Component` and `@EnableConfigurationProperties`, these components
are no longer registered even though explicitly included.

* pr/16730:
  Fix 'spring.resources.cache.period' for WebMvc

Before this change it got overwritten by forwarding an empty
CacheControl to Spring. Spring itself sets CacheSeconds already
correctly in absence (=null) of a CacheControl.

Also:
* Fixes bug in WebMvcAutoConfigurationTests.cachePeriod which
prevented it to assert anything

Previously, due to a quirk in Spring Framework, it was necessary to use bean method
proxying in @Configuration classes that define one or more FactoryBeans. This quirk has
now been addressed so this commit disables bean method proxying where it is now no longer
needed.
